PIS probs - warning lights/error codes

Have been having cascading problems since installing PIS 10kWh system in April. Early system shutdown, failed BMS boards, then triggering of Prius warning lights. The latter required disconnecting the 12v battery to 'reboot' and cancel them per Robb of PIS. But then, when attempting to do an electrical load test using air con & other accessories, we triggered several yellow warning lights that do no go away with a reboot. Have been told that we need to have a dealer read the codes to troubleshoot. Stuck between high cost of dealer service who may know little/nothing of the PIS impact, and few/far between hobbyist installers who can help figure this out. Major bummer not having this $10k system work, and now it may be impacting the standard operation of our Prius.

I live in VA, but am in northern NY working for the summer. Anyone in either area with ability/willingness to read those codes for us, or help troubleshoot in any way, or any advice/insight at all - is desperately sought and appreciated.

At the end of our rope...

 

Thx for the tip on the auto parts stores. We've been consulting w/Robb throughout this process. He has tried. But he's said he's never before seen our current symptoms - has no idea regarding the yellow warning lights. I'd like nothing better than to say that we love our PIS system. But it's been on the fritz since we installed it, and has grown increasingly problematic.
